FINE LOG INTERPRETATION MODEL OF PHYSICAL PROPERTY PARAMETERS OF LOW- PERMEABILITY RESERVOIRS IN GAOYOU SAG BASED ON LOGGING ATTRIBUTE ANALYSIS

It is very difficult and important to accuratelydetermine physical property parameters of low- permeability reservoirs on the conditions of existing accuracy of logging data. In order to improve the logging interpretation accuracy of physical property parameters of low- permeability reservoirs and provide higher accurate parameters for numerical simulation and reservoir evaluation,taking Member Fu- 3 of Funing Formation in the slope of Gaoyou sag as an example,Member Fu- 3 formation was divided by using the of logging attribute analysis,the interpretation modes of physical property parameters in each section were established separately. The error analysis was carried out by core hole. The results showed that the interpretation accuracy of reservoir physical property parameters was improved greatly and the approach to establishing fine interpretation model of physical property parameters of low- permeability reservoirs was effective.
